* Initial work on JSON builder

* moving the files back to ondemand for now.

* tweak

* more later

* update

* minor edits

* dropping vs arm (missing support)

* adding tests. we still specialized write_string_escaped

* tweaking

* fix typo

* tweaking the approach

* minor fix

* missing store

* another missing store

* Attempt at fixing failing serialization tests. (#2292)

* Fixing appeand_float typo (#2294)

* applying a couple of fixes

* updating single header

* fix for pre C++17 if constexpr

* Fixing unused argument problem and updating the singleheader file

* various pedantic fixes

* Sketch of builder

* reordering.

* simplify

* Adding draft of static reflection based deserialization

* Updating simdjson singleheader

* patching the automated deserialization.

* automated

* Adding support for smart pointers of user defined types.

* Adding specialization for smart pointers for basic types. I think it is highly likely that this can be done in a more generic way.

* Referncing a later version of rapidjson that fixed the issue related with assignment attempt of a const variable for GenericStringRef class.

* guarding the tests

* adding documentation for string_builder

* saving

* rename to 'append'

* saving

Daniel Lemire a05a56856d fix: use On-Demand throughout. (#2222) 2024-07-29 15:54:21 -04:00
strager d036fdf919 Reduce #include bloat (<iostream>) (#1697)
Including <iostream> has two problems:

* Compile times are worse because of over-inclusion
* Binary sizes are worse when statically linking libstdc++ because
  iostreams cannot be dead-code-stripped

simdjson only needs std::ostream. Include the header declaring only what
we need (<ostream>), omitting stuff we don't need (std::cout and its
initialization, for example).

This commit should not change behavior, but it might break users who
assume that including <simdjson/simdjson.h> will make std::cout
available (such as many of simdjson's own files).
